MACHINE FOR WINDING AND SPINNING YARN.

Specification of Letters Patent.

Patented Nov. 20, 1906.

Application filed March 16, 1906.- Serial No. 306,454.

T0 on whom it may concern.-

Be it known that we, ELI NEILD, a citizen of the United States, and HENRY MARsH, a subject of the King of Great Britain, both residing at New Bedford, Bristol county, Massachusetts, have invented certain new and useful Improvements in Machines for WVinding and Spinning Yarn, of which the following is a specification.

Our invention comprises improvements in means for automatically adjusting the nut on the quadrant-screw of self-acting spinning and winding mules to decrease the tension on the yarn whenever the tension exceeds a predetermined amount. In Patent No. 778,698, granted to us on December 27, 1904, we have shown mechanism for this purpose.

Our present invention relates to improved means for accomplishing the same result, and in carrying out our present invention we employ substantially the same means actuated by the tension of the yarn for causing the ad justing mechanism to act as are shown in said patent, although the adjusting mechanism is differently constructed and arranged and adapted to give a greater movement to the adjustingscrew than thedevices of the patent referred to.

In the accompanying drawings, which illustrate our invention, Figure 1 is a side elevation of as much of a spinning-mule as is necessary to illustrate our invention. Fig. 2 is a sectional view taken on the line 6-9 of Fig. 1, and Fig. 3 is a perspective view of the holding-pawl and the sleeve and arm by which the pawl is carried.

Referring to the drawings, C and D indicate levers connected to the faller-shafts C and D, respectively. A chain F, having its ends connected to studs C and D? on the levers C and D, extends around an antifrictionroller arranged within a yoke G, as shown, and a catch H is suspended from the yoke G and is adapted to slide vertically in a bracket J, fixed to the carriage K. When the tension on the yarn becomes excessive during the inward run of the carriage, (in the direction of the arrow A,) the levers C and D are depressed, thereby permitting the catch or drop lever H to move downward by gravity from its normal position and engage a proj ection L on the rod Y, which is arranged to slide in bearings M and N, and thus move the rod a short distance to the right at the end of the inward run of the carriage. Upon the succeeding outward run of the carriage (in the direction of the arrow A) the latter engages an arm U, projecting upward from the rod Y, and restores the rod Y to its normal position.

The mechanism just described for effecting the movement of the rod Y is substantially the same as shown in our patent above referred to; but the devices operated by the rod to adjust the nut on the quadrant are differently constructed and arranged. As shown, a bracket E is secured to the standard U uponthe rod Y,'and this bracket has a laterally-projecting stud or pin E adjustably secured within a slot E in the bracket. Upon the horizontal shaft T, which supports the quadrant-screw V, is arranged a loosely mounted sleeve P, having thereon an arm P, to which is pivoted a pawl Z, having an inclined face 2. A chain X has one end secured to a bolt U on the standard or upright arm U, and this chain extends from the bolt U once around the sleeve P and is secured to the sleeve by a set-screw X at the end of this one turn. From the set-screw X the chain extends to a fastening-bolt B upon a standard B, arranged upon the rod Y at the opposite side of the shaft T and sleeve P. In the normal positions of the parts (shown in Fig. 1) the pawl Z rests upon the pin E and is thus held out of engagement with a ratchet R upon a bevel-gear S, which is rotatably mounted upon the shaft T. This bevel-gear meshes with the gear Q, secured to the lower end of the quadrant-screw.

During the inward movement of the carriage if the tension on the yarn exceeds a certain amount the levers C and D, connected to the faller-shafts are depressed, and the droplever H engages the projection L near the end of the run, and thereby moves the rod Y in the direction of the arrow A. This movement of the rod Y draws the supportingpin E in the same direction, and the pull exerted upon the chain X by the standard U causes the sleeve P to rock backward or in the direction to move the pawl off of the supporting-pin. In other words, the pin and pawl move in opposite directions when the projection L is engaged by the drop-lever H. As soon as the pawl leaves the supporting-pin it engages the ratchet B. At this time it will be understood the carriage is at the end of its inward run and the quad rant-screw is inclined toward the carriage. Upon the succeeding outward run of the carriage the ratchet R and gear S are IIO held stationary by the pawl Z until the carriage engages the standard U. During this outward movement the quadrant screw moves from the inclined to the upright position, and as the bevel-gear S is held stationary the gear Q on the quadrant-screw must rotate and this rotation of the quadrant-screw raises the nut W, thereby releasing the tension on the yarn. When the carriage in its outward movement strikes the standard U, the supporting-pin E is moved toward the inclined face of the pawl, and the pawl is simulta neously moved toward the pin by the rotation of the sleeve P, this rotation being accomplished by reason of the chain connection between the sleeve and the standard B, which moves with the rod. The adjustment of the nut is thus effected while the carriage is moving outwardly, and the parts are brought to their normal positions at the end of the outward run. It is evident that an outward adjustment of the nut will take place automatically whenever the tension on the yarn exceeds a certain amount. A spring Z is provided for the purpose of pressing the pawl toward the teeth on the the ratch et-wheel.

What we claim is 1. In a machine for spinning and winding yarn, the combination with the mule-carriage, the shaft, the quadrant and screw, the nut on the screw and a gear fixed to the lower end of the screw, of a gear and a ratchet connected together and rotatable with respect to the axis of the shaft, a pawl rotatable with respect to the axis of said shaft and adapted to'engage the ratchet, a sliding rod having a support for lifting and holding said pawl out of engagement with the ratchet, connections between said rod and pawl whereby a movement of the rod will cause the pawl and its support to move simultaneously in opposite directions, and means controlled by the tension on the yarn for actuating said rod to release the pawl from its support.

2. In a machine for spinning and winding yarn, the combination with the mule-carriage, the shaft, the quadrant-shaft and screw,

the nut on said screw, and a gear fixed to the lower end of the screw, of a loosely-mounted gear concentric with the axis of said shaft and engaging the gear on the screw, a ratchet connected to said. loosely-mounted. gear, a sleeve rotatable about the axis of said shaft, a pawl connected to said sleeve and adapted to engage the ratchet, a sliding rod having a support for lifting and holding said pawl out of engagement with the ratchet, connections between said sleeve and rod whereby when the rod is moved in one direction said support and pawl will move toward one another and when the rod is moved. in the opposite direction the pawl and support will move away from one another, and means controlled by the tension on the yarn for actuating said rod in the direction to release the pawl from the support.

3. In a machine for spinning and winding yarn, the combination with the mule-carriage, the shaft, the quadrant and screw, the nut on the screw and a gear fixed to the lower end of the screw, of a gear and a ratchet connected together and rotatable with respect to the axis of the shaft, a sleeve rotatable with. respect to the axis of the shaft, a pawl connected to the sleeve and adapted to engage the ratchet, a sliding rod having a support for lifting and holding said pawl out of engagement with the ratchet, a flexible band or chain wound upon said sleeve and. having its ends.

connected to said rod at opposite sides of the axis of the sleeve, means'controlled by the tension of the yarn for actuating said. rod in one direction at the end of the inward run of the carriage, and means upon the rod for engaging the carriage at the end of its outward run.

In testimony whereof we aflix our signatures in presence of two witnesses.

ELI NEILD. HENRY MARSH.
